Region of Impact: Global



Problem: Yields of rice, the most important crop for over half of our planet, are catastrophically reduced during floods. Because rice provides up to two thirds of the diet of many people in the developing world, many who live on less than $1 day, these losses have devastating impacts on farmers and their families.

Solution:  Identification of a submergence tolerance gene and precise introduction of the gene into locally adapted varieties favored by farmers using modern molecular breeding.

Impact:  In 2011, 1,000,000 farmers grew Sub1 rice, with millions more expected in the next few years. Yields of Sub1 rice are three to five folds greater than conventional varieties during floods.
